At the boiling point, molecules begin to move from a liquid to a gaseous state. For individual molecules, this process (evaporation) can occur at temperatures lower than boiling.
*There is still additional energy required (called the heat of enthalpy) and there must be a nucleation point from which the molecules move. Lacking these, water can reach temperatures higher than the boiling point without becoming a gas.
What else can I help you with?
When water boils it becomes steam its particles spread out and occupy a greater volume has its density increased or decreased?
When water boils and turns into steam, its particles spread out, occupying a greater volume. As a result, the density of steam is decreased compared to liquid water, because density is defined as mass per unit volume, and the same mass of water now occupies a larger volume as gas.
Which has the most energy particles in steam particles in liquid water particles in ice or particles in freezing water?
Steam has the most energy as its particles are in the gaseous state and move faster than particles in liquid water or ice, which are in the solid or liquid state respectively. Freezing water has a similar amount of energy as liquid water since they are at the same temperature.
When steam turns to water the particles get?
When steam turns to water, the particles lose energy and slow down, coming closer together. This causes the steam to condense into liquid water.
When a pot boils steam is give off. why is this so?
When a pot boils, the water inside reaches its boiling point, which is 100°C (212°F) at sea level. At this temperature, the water molecules gain enough energy to transition from a liquid state to a gaseous state, forming steam. This steam is essentially water vapor that escapes into the air as the liquid water converts to gas. The release of steam indicates that the water is undergoing a phase change due to the added heat.
What gas first appears as a colourless gas then when cooled it condenses into a colourless liquid and boils at 100 degrees celccius?
The most probable answer for your your question is pure water.
When water boils it becomes steam its particles spread out and occupy a greater volume has its density increased or decreased?
When water boils and turns into steam, its particles spread out, occupying a greater volume. As a result, the density of steam is decreased compared to liquid water, because density is defined as mass per unit volume, and the same mass of water now occupies a larger volume as gas.
Does liquid water boils as it turns to ice?
Steam condences into water, water freezes in to ice, ice melts into water, water boils to steam
What happens to water when it boils?
it gets hot
What is the steam point of the Celsius scale?
at 100 degrees liquid water will go to steam and steam will go to liquid water
Which has the most energy particles in steam particles in liquid water particles in ice or particles in freezing water?
Steam has the most energy as its particles are in the gaseous state and move faster than particles in liquid water or ice, which are in the solid or liquid state respectively. Freezing water has a similar amount of energy as liquid water since they are at the same temperature.
What happens to particles as a liquid boils?
As the water heats up the pot you're boiling it in, the particles of the water receive more energy. The more energy the particles have, the faster they move and the farther they spread apart. When the water finally reaches 212 degrees Fahrenheit (100 degrees Celsius), its particles spread so far out that they make the transition from a liquid to a gas. Thus, making steam.
Does the temperature of a boiling liquid increase as it boils?
No. Take water for example. Water boils at 100 degrees C. When water boils it becomes steam. This steam as soon as it is released is 100 degrees C also. The boiling point for a liquid is the point when it becomes a gas.
What happens to particle in liquid water when the water boils into steam?
Assuming they are non-volatile, solids in liquid water will remain in the water when it boils. This is the process of distillation, where the solids and non-volatile matter is separated from the water, and is left behind as the water evaporates off.
What happens to particles when a liquid boils?
the particles are given more energy.
What happens to the mass of water in a tea kettle when it boils?
The liquid mass is partly converted to a gas (steam, water vapor), so if this escapes, the mass is no longer there. The steam can, however, be captured and condensed, and used again (as in steam engines).
When steam turns to water the particles get?
When steam turns to water, the particles lose energy and slow down, coming closer together. This causes the steam to condense into liquid water.
What Happens to particles when steam condenses?
When steam condenses, its water vapor particles lose thermal energy and come together to form liquid water particles. This process releases heat, which is why condensation is accompanied by the release of latent heat energy.
